Again, that number is very misleading. Apple is "lying with statistics" basically.
No attacker trying to break into your iPhone's authentication will use random images. They'll build a profile off your existing online photos, and then try to fool the FaceID system that it's actually you authenticating.
Suddenly that number drops by about three or four orders of magnitude.
This is harder to do with fingerprints because you don't keep your fingerprints online.
- jmull 9y agoPeople probably don’t post a lot of 3D infrared scans of their face online, which is what FaceId uses. (They also don’t leave them all over on the things they touch, like they do with finger prints.) Also, I don’t know of your “lying with statistics” claim is fair. Of course, statistics are a great way to lie since you can have a mathematical certainly that what you are claiming is numerically accurate while at the same time give a false impression through selecting the numbers to present. However, in this case, the implication is that FaceID is more precise and secure than Touch ID, which is probably true if it works the way they claim. (Well, we don’t really know that yet, but we don’t know the opposite yet, either.)
- mikeash 9y agoThey’ll pull fingerprints off your phone to defeat Touch ID. Unless the photo attack is substantially better (and given the 3D scanning tech used by Face ID, I doubt it), Face ID is still a win. Edit: why “again”? What was the last time?
